Figure 6
Axial-symmetric morphing of the zb-/diamond-structure NWires growing along the [111] axis with a hexagonal cross section and six {110} interfaces. The nominal cross section for i = 8 is shown by white `ghost atoms' at the top interface and by the yellow atoms in the lower half of the cross section. Reductive morphing with j1 = 2 was applied to the top interface, while morphing to maximum expansion with j2 = −i = −8 was applied to the bottom interface. For atom colours, refer to Fig. 4. For a detailed geometrical derivation of characteristic lengths and areas, refer to Appendix C. |
